CD Alternative

At present I have around 1200 CD's which are played on a Cal Audio/Benchmark DAC 1.  I am looking for some guidance regarding the potential use of high res streaming or ripping and having a server.  I have no idea which option/equipment to pursue or if there is another option to consider.  This all started when I recently went to audition speakers with a few CD's but discovered this was the old fashioned way and instead used a "Roon Streamer" I think.   Secondly the Cal Audio is about 25+ years old and the DAC 1 is 16 yrs old.  Thanks in advance for your responses as I am absolutely confused with the digital path to take.
